Battery 12 Ah/Security grade 3
Instruction manual PSV 2415-12
DESCRIPTION
PSV 2415-12 is an up-to date power supply unit with battery
backup compliant with EN standards. Unit provides all features
required by EN 50131-6:2008, security grade 3.
Distinctive and unique feature of PSV 2415-12 is invented by
Alarmtech ViP mode –Voltage-in-Parallel. Power supply units
with ViP feature can be connected in parallel both (+) and (-) on
one common power bus without a need of additional synchroni-
zation. Connected units will share load on a bus. ViP feature can
be used to build distributed and redundant power systems. It can
be also used to compensate voltage drops on a bus by placing
power supply units in distant bus sections.
Power conversion is based on high frequency SMPS regulator
providing high conversion efficiency. Low losses inside unit pre-
serve batteries from overheating shortening battery life time.
Computerized battery recharging circuit works in constant poten-
tial –limited current mode –the best mode to provide the longest
possible battery life time.
Power unit is equipped with built-in diagnostic system detecting
and signalling mains failure, different battery failures including
end-of-life warning, output faults like low voltage or broken fuse.
APPLICATIONS
Power supply system for 24 V installations

0.74 A (12 h in battery mode with 12 Ah batteries)
Total rated maximal output to installation: 1.0 A
Battery recharging current –0.5 A, providing recharging time
below 24 h
Total current capacity of power unit –27.6V, 1.5 A
ViP (Voltage-in-Parallel) feature increasing reliability and ca-
pacity of power supply systems –power supplies with ViP fea-
ture can be connected in parallel to same bus without need
for additional synchronization

batteries
Short circuit and overload protection
Detection of no mains supply (EPS fault)
Detection of different battery faults (APS fault) –not con-
nected, low voltage, high internal resistance
Detection of low output voltage (OUT fault)

Power Unit PSV 2415
PSV 2415-12 power supply installation and start-up procedure:
Fix unit in destination place using 4 fixing holes
Place two sealed lead acid batteries 12 V/ 12 Ah in battery
chambers
Make internal connection in battery pack connecting left bat-
tery (-) with right battery (+)
Make connection between right battery (-) and battery con-
nector using black battery cable connected to BAT-
Make connection between left battery (+) and battery con-
nector using red battery cable connected to +BAT
Make appropriate connections between power output and
power receivers
Make required connections between signalling outputs of PSV
2415-12 unit and cooperating units (outputs EPS, APS, OUT,
SAB, input –SDT*)
The socket outlet delivering 230 VAC shall be installed near
the power supply unit and shall be easily accessible
Make sure that cable delivering 230 VAC to power supply is
disconnected from mains
Carry in cable delivering 230 VAC to the unit using separate
mains cable entry on the left side and connect it to 230 VAC
input of PSV 2415 power unit –make sure that PE cable is
connected to PE input
Switch on mains delivering energy to power supply - PSV
2415-12 unit will start automatically delivering power to the
load and monitoring state of PS

2. TECHNICAL DESCRIPTION
2.1 Front panel
Power supply unit is equipped with front panel showing actual general state of unit. Three LED’s display shows:
Green LED: mains voltage present –unit in EPS mode supplied from mains
Yellow LED: mains voltage missing –unit in APS mode supplied from battery
Red LED: fault detected –quick visual identification and localisation of failure is possible with help of set of diagnostic LED’s
in power unit
2.2 Internal state monitoring functions in power units
All monitored states of PS are displayed with help of LED diodes for quick visual identification. The placement of monitoring LED is
documented in below placed drawings. The meaning of LED colours is following:
Green - normal state, OK
Red - fault detected
Yellow - informative meaning (neutral)
